W'ILLIAM STRAIT, OF ELMIRA, NElV YORK.

PLOW.

SPECIFICATION forming part of Letters Patent No. 469,756, dated March 1,1892.

Application filed April 25, 1888. Serial No. 271,795. (No model.)

To all whom it may concern:

Be it known that I, WVILLIAM STRAIT, a citizen of the United States,residing at Elmira,

to the accompanying drawings, and tothe figures of reference markedthereon, which form a part of this specification.

Figure 1 is a side elevation of a plow to which I have applied myimprovements. Fig. 2 is a plan view of the same. view and sectionthrough the handles. Fig. 4 is a detached section hereinafter referredto. Fig. 5 is a detail perspective view showing the colterorjointershifting mechanism. Fig. 6 shows one of the arms of the mold-boardlatch. Fig. '7 is an elevation of the rotary shifting colter. Fig. 8 isa plan view of the plow-saddle. Fig. 9 shows another form of colter.Fig. is a plan of the pivotal plate,

to which the handles are attached. Fig. 11

is an elevation of the substitute colter-shifting arm.

My invention consists in the following construction and combination ofthe parts, which will first be fully set forth, and the new features ofthe plow then described in the claims.

In the drawings, 1 represents the plowbeam.

2 is an adjustable standard carried on the clevis end of the beam andsecured rigidly by means of a bolt and ribs formed on the side of thebeam or on the clevis-iron.

3 is the trailingwheel, having its bearings in the arm 4:.

5 is a bolt uniting standard 2 and arm 4., so that there may be alimited vibrating movement of the latter to enable the wheel 3 to adjustitself to the line of movement of the plow andparallel thereto.

6 is the plow-standard.

7 is the bearing in which the jointer or colter works.

8 is the usual reversible mold-board, which is adapted to swing to theone side or the other of the plow.

9 is the plow-point.

Fig. 3 is a rear 10 is the saddle, to which the point and mold-board aresecured.

11 is the pivoted latch, which is adapted to lock the mold-board inposition on either side of the standard.

12 are the two arms of the latch. These arms are detachable, and areprovided with a slot 13, through which and the latch proper passes abolt, so that the arms 12 maybe adjustable for wear or for anyinequalities or imperfections in the castings. This adjustment may beeffected by any equivalent way, such as making the latch movable on themold-board instead of adjusting the latch proper.

1a are the handles of the plow, which are pivoted upon the bolt 15.

16 is a plate at the inner end of the handles, to which thelatter arerigidly bolted, and which receives the pivotal bolt 15.

17 is an enlarged seat or bearing formed on the rear of the standard 6,upon which the corresponding seat 18 bears. The pivotal bolt 15 passesthrough the seat on the standard and plate, and thereby gives a firmhearing upon which the handles 14: may vibrate or oscillate.

19 are lugs formed on the inner ends of the plate 16, and which straddlethe central rib 20 on the upper edge of the standard 6 and limit themotion of the handles in either direction.

21 is a lug formed on the standard, under which the forward end of theplate 16 rests and holds the handles rigidly at the proper elevation.

22 is an arm rigidly bolted to the upper in ner end of the handles.

23 is a jointer-shaft.

24 is a vibrating arm, which is slipped upon the end of shaft 23 andheld in place by setscrews.

25 is a lug formed on the standard, which serves to hold the arm 24 andjointer-shaft 23 in place.

26 is a slot formed in the arm '24, within which the arm 22 works toshift the jointer 27 when the mold-board is reversed.

28 are lugsupon either side of the saddle 10, one of which bears firmlyagainst the upper side of the standard 6 when the point and mold-boardare shifted to either side of said standard. Instead of the lugs 28hearing against the standard direct, they may bear against either sideof the plate 16 or itslug's 19. When the mold-board is thus in place 5on either side, the latch device is thrown into engagement with thebifurcated end of the pivoted reversing-arm 29, and thus holds themold-board and the handles 14 rigidly in place to the one or the otherside of the plow. IO In this reversible or hillside plow I maysubstitute a colter for the jointer 27. (Shown on the plow.) To effectthis I make provision for the removal of the jointer-arm 23 and theinsertion of the colters. (Shown in Figs. [5 7 and 8.) As the colterdoes not need to be oscillated to the extent that is necessary whenusing the jointer, I employ the shifting-arm 30 (see Fig. 11) in theplace of arm 24. The set-screwin arm 24 is loosened and the jointer- :0arm 23 removed and either the colter 31 or 32 inserted in its place, asdesired, and the shifting-arm 3O slipped on theend of the colter-arm.

33 are arms on the shifting-arm 30,between which the arm or finger 22 onthe handles plays.

3t are lugs formed on arm 30, which bear against the standard above saidarm and serve tolimit its oscillation. It will be seen that 0 there isconsiderable lost motion between arm and finger 22, and that it travelssome distance between the arms 33 before it ,engages the shifting-arm30, when it moves it slightly to give the necessary inclination to 35the colter either way.

3.1 is a colter of the usual form.

32 isa rollencolter provided with the disk rotary knife 35, and isadapted to be shifted to either side.

0 The points or lugs 28 may be formed upon the. mold-board 8, instead ofon the saddle 10.

I claim- 1. In a plow, a standard, a jointer or colter arm, ashifting-arm thereon, and a lug formed on the standard, whichholds theshifting-arm in place, all in combination, as set forth.

2. In a plow, the pivoted shifting-handles, in combination with theplow-standard having a lug thereon which bears upon the inner end of thehandles and holds them against vertical displacement.

3. In a plow, the combination of the pivoted handles having stops upontheir inner ends to limit their movement, and the standard having aprojecting stop arranged between those on the handles.

4. In a plow, the pivotal plate to which the handles are secured,provided with lugs or stops upon one end and a latch-seat at the other.

5. The pivotal locking-latch for the moldboard, having locking-arms upon.the main body of the latch device, and means for adj usting the latchto take up the wear.

6. In a plow, the handles 14, the plate 16, having stops thereon, and abolt-seat, in com bination with the standard having an enlargedbolt-seat extension, and a bolt passing through the plate and standard,therebyrpivoting the plate and permitting. the oscillation of thehandles.

7. The combination of a pivotal double latch, a mold-board, and meansfor adjustably interlocking the latch and mold-board.

S. The combination, in a plow, of a standard, a reversible mold-board,pivoted handles, and a latch whereby the mold-board when locked in placeon either side also locks'the handle to the one side or the other.

In testimony whereof I affix my signature in presence of two witnesses.
